Compress PDF

• Outcome: Pass
• Latest audit: Jul 10, 2026 · 4:43 AM UTC
• Version: 1.0.0

Overview

This skill does what it says: it uploads a user-selected PDF to a named third-party compression service and returns the compressed file URL.

Install only if you are comfortable sending selected PDFs to Cross-Service-Solutions and receiving a third-party-hosted download URL. Avoid confidential, regulated, legal, financial, or personal documents unless you have approved that provider’s privacy and retention practices. Use a dedicated API key and do not paste it into shared logs or chats.

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep

Missing User Warnings

Medium

• Confidence: 96% confidence
• Finding: The README explicitly instructs users to upload their PDF documents to a third-party service but does not warn that document contents will leave the local environment and be processed by an external provider. PDFs often contain sensitive personal, financial, legal, or business data, so omission of a privacy/data-handling warning can lead to unintentional disclosure and unsafe use in sensitive contexts.

Missing User Warnings

Medium

• Confidence: 96% confidence
• Finding: The skill sends user-provided PDFs to a third-party service, but it does not present an explicit user-facing warning at the point of use about external transmission and third-party hosting of the resulting file URL. This is dangerous because users may unknowingly disclose sensitive document contents to an external processor, creating privacy, confidentiality, and compliance risk.

Missing User Warnings

Medium

• Confidence: 90% confidence
• Finding: The script uploads the full user-supplied PDF to a third-party service, but the code provides no explicit notice or confirmation at the moment of transmission. This is dangerous because PDFs often contain sensitive personal, financial, legal, or proprietary data, and users or higher-level agents may assume processing is local when it is not.

External Transmission
